The object of my invention is to provide a coin controlled mechanism of simp e, durable and inexpensive construction, which is especially adapted toy be used in connection with vending iquid fuels, such as gasoline.

A. further object is to provide a coin con trolled mechanism so constructed and arranged that the operation of the machine with counterfeit coinsor slugs will be practically impossible.

More speciiically it is the object ot my inf vention to provide in connection with liquid fuel vendingvn echanism, having hand controlled means for delivering predetermined quantities of liquid, means for locking the vending machine against further action ai'ter the said predetermined quantity of liquid has been delivered, and in connection therewith means actuated by the insertion of a coin through a coin receiving slot in tli casing for automatically releasing the vending mechanism when the said coin has been inserted.

My invention consists in the construction, arrangement and combination oi the various parts ot' the device, -whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanyino' drawings, in which:

The numeral 10 indicates an upright cylindrical support on which the gasoline vending mechanism is mounted, said mechanism comprising a. retaining tank 11 having outlet pipes 12 and 13. Each of said pipes includes a valve casing 1li in which the ordinary controlling valve is mounted, said valve being provided with valve stems 15. Each of the valve stems has an actuating arm 16, one end of each of said arms being provide-d with a set screw 17 designed to maire operative connection with a cani 18 mounted on the shaft 19. rlhe said shaft 19 is rota-tively vmounted in the vending inachine casing 2O and also in the casing the coin controlled mechanism 21. The forward end of the shaft 19 is provided with a crank 22, which provides means whereby when the said crank 22 is operated through a predetermined angle, the gasoli e controlled valve will be opened, permitting the gasoline to be delivered from the tank 11 to discharge pi )e 23 through the pipes 12 and 13, said discharge valve heine' moved to an open position when the crank 22 is in its downwardly extended position, as shown in Figures l and 2. A spring actuated catch 24 is provided for locking the said crank in said. ciosed position, said crank being locked in said position against the action of a spring hereinafter described. K I

is adapted to rotate to an angle olf substantially 180. The operaticm of the control valve, however, is completed in a trac.- t-ion of the entire movement of said crank. The spring is provided 'torninoving the controlvalve to an open position. n

Inthe drawings I have ilh'istrated two outlet pipes 12 and .13, each of which is pro vided with an independently controlled valve, and I have provided for each of the valve operating shafts 1 9 a coin controlled mechanism. Each of these coin controller` mechanisms, however, is alii-ze, except that one is designed to be operated by a coin of different value from that of the other. For this reason but one of the coin controlled mechanisms will be hereinafter described.

As clearly shown in Figures 1 and 2, the casing 2l of the coin controlled mechanism is mounted adjacent to one side of the casing 20 of the vending mechanism. Said c: ing 21 comprises a front member 26, a top member 27, side members 28 and 29 and a bottom member 30. The inner surface of the side member 2,9 is provided near its upper end with an inwardly extending lug k31 in which is provided ya coin receiving slot The member 31is provided with a slide bar 33 designed to move through the slot 32 in suc-h a manner as to close the same when in one position ot its movement. That por- 'tion of the bar 33 extending through the slot 32 hasa beveled face 34 so arranged that when a coin is placed in the slot 32, the bar 33 may be slid rearwardly. Means is hereinafter described for locking the said bar in its closed position while the coin is being passed through the coin controlled mechanism.

Beneath the member 31 is an inclined frame member 35, having in its upper end an inclinedjrecess 36. That portion of the frame yformin0r thek to of the recess 36 is b fu' i n provided with a groove 34 I* igures 3, (i,

16 and 17),and that portion forming the bottom of the recess 36 is provided with a' cavity 38 in which is mounted a pivot pin 39, pivotally mounted on which is an L-shaped lever having a vertical arm 40 and a horizontal member Q1. 41 is provided with a groove 42 which is vertically'below the groove. 37. The grooves 37 and 42 are arranged in a common plane and beneath the slot 32 so that as the coin is inserted through the slot 32 it will rest within the grooves 37 and 42.

The crank The member 37 and the plate 43 is equal to the diameter of the coin, just enough clearance being provided to permit the coin to move freel y through the groove.

The arm 40 is provided with a bending bar 44 designed to rest adjacent to the inner surface of the coin, while it rests in the grooves 37 and 42, the coin being shown by dotted.

lines in Figure 17. The upper end of the arm 40 provided with openings 45 and 46. The upper end of the frame 35 'is provided with a rotatively mounted shaft 47 which extends through the opening 46 of the arm 40 and is rotatively mounted in a sleeve 48 slidably mounted in an opening 49 in the frame member 35, said sleeve 48 being held against rotary movement. The shaft 47 is provided with a spring 5() also mounted in the opening 49, having'one end resting against the inner end of the sleeve 48. The forward end of the s ring 50 is designed to engage a collar 51, sait collar engaging the rear surface of the arm 40. The front end of the shaft 47 extends through the front plate 26 ofthe housing of the coin controlled mechanism,

and'has on its front end a. crank 52, said crank being provided with a pointer 53. Mounted on the shaft 47 between the plate 26 and the frame member 35 is a collar 54 having a helically shaped cam 55. The collar 54 serves to limit the shaft 47 against inward movement.

The rear end of the shaft 47 is provided with a head 58 carrying cam rollers 59.

Thus 1t will be seen that if the shaft 47 is rotated in a clockwise direction, as viewed yfrom the right hand end of Figure 17, the

head V58 will also be rotated, causing the cams 57 and the drum 56 and the sleeve 48 to be moved forwardly, causing tension to be applied to the spring 50, which in turn will slide the collar 51 and the ripper end of the arm 4() This will cause the bending bar 44 to engage the inner surface of the coin 60, causing the coin to be bent in the manner elearly'shown in Figure 16. .Tt will be seen that as the upper end of the arm 40 is moved forwardly, the 'free end of the member 4l being moved downwardly and the depth of the groove 42 decreased. If a counterfeit coin is being used, which is considerably softer than the genuine coin, this bending operationwill be continued until the top edge of the stripper plate 43 is even with the top edge of the groove 42, which will permit the lower edge of the coin to be thrown forwardlj' in the direction of the arrow in Figure 16,

llt)

and to be thrown out of operative relation with the mechanism for controlling the operation of the shaft 19 hereinafter described. The tension of the spring is such that the spring will yield `before the genuine coin is bent suficiently to be thrown from the groove 42. The tension of the spring 56 should also be suoli that the elastic limit of the metal of the coin will not be reached, so that the coin will assume its original position as soon as thebending tension is released.

Thecoin 60 is retained within the grooves 37 and d2 against downward movement while the bending operation takes place by means of a stop pin 61 (see Figures 3 and 6). Said stop pin is slioably mounted and arranged transversely with the coin. The inner end of the pin 61 is pivotally connected to a lever which in turn is pivotally mounted to the frame member 35. he free end of the lever 62 is designed to rest against an adjusting screw 63 mounted in the slide bar 33 (sce Figure 10). By this arrangement it will be seen that ,as the coin is placed in the slot 32, the slide bar 33 will be moved rearwardly, causing the pin 61 to be moved to the position whe-re it will'be engaged by the coin 60, which movement is illustrated by dotted lines in Figure 10.

The front face of the cam drum 56 is provided with a forwardly projecting pin 64, which is also adj ustabl'y mounted in said cam. As the cam 56 is moved forwardly by the rotation of the crank 52' and at the time it has reached its forward limit of movement, the pin 64 will engage the free end of the lever 62, causing the rol 61 to be withdrawn and the coin relY ased. Afit the same time the bar 33, which is also actuated by the lever 62, will be moved to its closed position. ln this connection it should be noted that the bar 33 has been in an opened position during the time the coin is within the grooves 37 and l2.

Slidably mounted in the upper end of the frame 35 is al bar 65 having a shoulder 66 resting against the forward face of the arm L10, s id bar 65 extending through the opening 15. The forward end of the bar 65 also rests against thc am 55. Said cam 55 provides means whereby the arm l() will be returned to its initial position ofmovement.'

Thus it will be seen that l have provided means whereby a. large number of counterfeit coins and slugs may be rejected from the machine, due to the fact that they are usually made of softer material than the genuine coins. Iron washers, however, are often used in machines, which are' stiffer than the genuine coins. Means has been provided for removing iron washers, which will hereinafter' be described. f

The lower end of the frame member 35 comprises a yoke having downwardly eritending members 67 and 68.V The members 68 isprov'ided with inwardly extendinghori- Zontal portion 69. The member 68 is also provided with a horizontally and inwardly extending portion 70, said members being spaced apart and substantially parallel with each other. The inner ends of the members 69 and 70 support a vertically extending frame member 7l. Said frame members are supported in the casing 21 by means of lugs 72 shown in Figure 3. The lower ends ofthe members 67 and 68 are designed to rotatively support the valve operating shaft 19.

Referring to Figure 18, it will be seen that the shaft 19 is formed in two sections, the adjacent ends of two sect-ions bein T spaccd a slight distance apart and joined together by means of a disk 73, said disk being provided with a slot 711 extending diametrica-lly through its center. The diameter and thickness of the slot are slightly greater than the diameter and thickness of the coin to be used in' the machine. Said disk 73 is provided with hub members 75 for receiving the adjacent ends of the shaft 19, said ends being rigidly secured therein. The forward one of the hubs 75 is designed to rotatively carry a disk 76, said disk having its inner surface provided with an annular groove 77 Said groove 77 is designed to supporta spring 78, one end of said spring being designed to rest against a lug 7 9 fixed to the member 76. The other end of the spring 78 is designed to rest against a lug 8O supported by the disk 73 and extending into the groove 77. By this arrangement it will be seen that the vdisk 76 will be yieldably carried by the disk 73. rlhe disks 73 and 76 are mounted between the frame members 67 and 68 in the manner clearly.

shown in Figure 3. The disk 76 has its periphery provided with a notch 81, while the disk 73 is provided with a notch 82. The inner face of the disk 73 is alsokprovided with a lug 83 (see Figure 8). The central portion of the periphery of the disk 73 isprovided with a serrated surface 811. The slot 74k of the disk 73 is located in alinement with the slot 32. The frame'member 71 is provided with bearing members 85 designed to support a rotatively mountedvertical shaft 86, said shaft being designed to carry a coin receiving gate 87, comprising a pair of parallel side members which provide a `coin receiving slot 88 between them, said slot being designed to lie in a common plane with the slots 32 and 74, and designed to receive the coin as soon as it has been released from the pin 61. One of the side members of the gate 87 is provided with an outwardly extending arm 89 designed to rest adjacent to the rear face of the disk 73 when in Aalinement with the lug 83, as clearly shown in Figure 8.

The vertical frame member 71 is provided with a pair of rollers 90 which serve to form a. guide for a vertical bar 91, said bar being also operatively mounted in stationary guide members 92. The' bar 91 is provided with an Cil per end of the fla-nge 93 is provided with al notch 95, while the upper end of the bar 91 is provided with a laterally and outwardly extending lug 96 asshown in Figures 8 and 11. Pivotally mounted in the lower edges of the frame members 69 and 70 is a shaft 97 designed to support a lever 98, the upper end of VVwhich is provided with a slot 99 in which is mounteda roller 100. The periphery of the roller 100 is also serrated. kThe lower end of the lever 98 is provided with a link 101 which has its outer end screwthreaded and extends through the lower end of the bar 71. Lock nuts 102 are provided so thatthe rod 101 may be adjusted therein, which in turn will adjust the angle of the lever 98 and the position ofthe roller-100 relative to the flange 93 and the disk 73. The surface 84 provides a. back for the slot/88, whilethe roller 100 serves to provide a bottom for the same.

The parts are so arranged that when the Y coin y is dropped into the slot 88, its front edge will rest against the serrated portion of the disk 73 with its bottom edge on the roller and its back edge against the iange 93, the serrated surfaces having the same number of grooves to the inch as the "coin yso. the serrations of the coin will register y locking lever 103 having an upwardly exa. the,4 disk 73.

tending arm 104. The free end of the member 103 is provided with a forwardly extending lug 105 designed to enter the notch 81 of the disk 76. The free end of the lever 103 is also provided with a spring actuated dog 106 designed to enter the notch 82 of The upper end of the arm 104 is provided with an inwardly extending lug 107 designed toy enter the notch 95 of the bar 91 when the said bar is in its elevatedposition of movement. The upper end of the arm 104 is also provided with a cam- 108 havinga beveled surface 109 designed to aetuate a bar 110 mounted on the upper end of the shaft 86. v A spring 111 is provided for yieldably supporting the upper end of the arm 104 to its inner limit of movement with the free end of the lever 103 atV its upper limit of movement. A spring 112 is provided for retaining the gate 87 to a position with the slot 88 in alinement with the slot 74.

Secured to the lower edge of the frame member .70 is a lug 113 to which is pivoted a magnet supporting bar 114 having at its upper end a yoke 115 in which is mounted a bar magnet 116, said magnet being adjustably mounted therein by means of a'set screw 117. One end of the magnet lies adjacent to the path of'travel of the coinV through the slots 32 and 88. A spring 118 is provided for yieldably supporting the magnet to its inner limit of movement. The support 114 is provided with a horizontally arranged bar 119 (see Figure'3), the inner end of which is provided with a downwardly extending lug 120.. The lug 120 is designed to be supported normally in the path of the cam 121 mounted on the disk 122, said disk being rrigidly secured to the shaft 19. l

The operation of my device is as follows: The operation of the device for testing the resiliency of the coin has already been described, which is operated through the lever 52. The coin 60 is delivered to the slot 88 of the gate 86. Assuming that the coin is nonmagnetic, then it will be delivered to the p0- sition shown in Figure 6. The operating arm 22 rests normally in its lower limit of movement and within the latch 24. The initial operating position, however, of this lever, as far asthe coin tester is concerned, starts with the lever 22 in its upper limit of movement, as shown inthe right hand unit of Figure 1. W'hen the said lever is in an upright position, the disk 73 will be in the position shown in Figure 6. The lever 22 will then be rotated in an anti-clockwise direction, causing the disk 73 to be rotated, which in turn will cause the coin 60 to be rotated and the bar 91 elevated, due to the meshing of the teeth of the corrugated surfaces. If the coin is genuine, ythen the bar 91 will be elevated until the slot 95 is in alinement with the lug 107, at which time the notches 81 and 82 will also be in alinement with the lug 105 and the pawl 106. The spring 111 will then cause the lug 107 to enter the notch 95 and the lug 105 and the pawl 106 to enter their respective notches. The upper end of the arm 104 will also pass beneath the lug 96, to positively lock the bar 91 against downward movement. This will take place afterthe crank 22 has been rotated through an angle of approximately 90"` or until the opposite end of the serrated lsurface 84 is in engagement with the coin.

100, thereby permitting the coin to drop toV the interior of the casing 21.

It shouldbe noted that at this point of the operation the set screw 17 of the valve actuating arm 16 has not reached its upper limit l (IU i l (l vtical position.

.for a new cycle ofoperatiomat of movement. In fact, when the disk 73 is in the position shown in Figure 1l, and atthe time the coin is being discharged from the (gate, the gasoline valvey is in a closed posi-v tion, so that further movement of the crank n 22 1s necessaryin order to open the gasoline valve. This is permitted by disengagement between the lug 83 and the arm 89 above described. 'A further movement of the arm 22 will cause the valve to be opened and gasoline delivered in any desired quant-ities, the crank being moved intoengagement with the latch 24, whichprovides means for auton'iatically retaining the valve in an open position until the measured quantity of gasoline has been delivered.

- Referring to Figure 11 it will be seen that the lug 105 is still retained within the notch 81. VMovement of theshaft 19', however, is permitted due to the presence of the spring 78 Within the slot 77 The disk 76 is held stationarywhile the disk 7 3 is permitted to rotate. The spring 78 serves to automat- Vically Vclose the valve in case the operator should accidentallylet loose of the crank before the entire amount of the measured quantity of gasoline has been delivered and before the crank 22 has been moved intothe latch 24. The'device may again beplaced in an operative position by simply releasing the latch 24, which will close vthe valve, after which the crank 22 may be movedto its ver- Wlien the lever is thus released, the disk `73 will rotate in a clockwise direction, as viewed in Figures 6, 7 and 11, until the notch82 has been engaged bythe lug1106, this movement being accomplished by the spring 78. A further movementof the lever 22 in a clockwise direction will cause the disk 73 to be rotated and the pawl 106 to be moved downwardly on account of its engagement withthe notch 82. This will cause. the free end of the lever 103 to be lowered land the'upper end of the arm 104 to be moved outwardly, causingthe lug'107 to disengage the'notch 95, V.permitting the bar 91 to move to itsl'ower limit of movement. At 'the same time the cam 108willdisengage the bar 100 permitting the gate 87 to be moved torwardlyto its normal'position with the slot 88m alinementwith the slot 36, causing the mechanism toreturn toitsnormal position of movement. The machine is then in position which time al coin maybe placed inthe slot 32, the lever 52'operated and the coin bending mechanism voperated as before described;V If'the coin inserteds'houldbe aV slug instead of a genuine c oin and provided with a smooth edge instead of aserrated edge, then the com will be delivered to the slot 88 in the same manner as a genuine Acoin, the only difference in ope eration being ,that the bar 93 will not be lifted' sufiiciently, if' at all, to permit the lug l017'to enter the notch 95 and no movement would be imparted to the gate 87, the machine being locked against any Vfurther movement with the exception that the slot 74 will be moved into alinementV with the coin as shown bydotted lines in Figure 7, at'which time the slug will pass through said slot by gravity and enter the passage ,123 which leads to a receptacle 124 projecting from the side of the casing 21 for receiving the slug. An opening 125 is -provided in said receptacle for the removal of the slug. Thus it will be seen that any slug having any irregularities, whereby the bar 91 is not lifted to its complete elevated position, will be delivered to the receptacle 124. i If an iron washer or slug is inserted in the slot 32, it will usually be passed to the slot 88, due to the fact that it is stiifer than the genuine coin. In this case, however, the coin passes so close to the inner end of the maghet 116 Vthat the coin is retained adjacent to said magnet andr is not delivered directly to the 'position of the coin shown. in Figure 6. The shaft 19 is rotated in the usual manner which will cause the cam 121 to be rotated and to engage the lug 120, thereby causing the magnet 116 to be moved inwardly and the coin stripped therefrom, due to the fact that a portion of it lies within the slot 88. 4The coin will then fall to theV position shown in Figure 7. It must be borne in mind that the disk 7 8 has made a partial rotation and that the bar will only be partially elevated to :its upper limit, which willresult in the iron slug being delivered to the receptacle 124.

Thus it will be seen that I have provided a coin controlled mechanism which may be used in connection with vending machines, Ysuch as used to distribute gasoline, and which is positive in its action, and which has the ability to discharge a large percent of slugs or counterfeit coins, and which is 'adapted to be used in connection with different types of vending machines. f
